<0> eval: 10 / 8 * 3600 * 24 * 30 / 1024
<1> buu: Return: 3164.0625
<2> integral: well i am not sure about that and i can't offend them. i need to simply (and gracefully) "protect" them from doing it by "mistake"
<2> integral: there must be a way, ff
<2> s
<3> toany: and yeah, of course if someone is trying to smash the system you remove their access bits right away
<4> bluebeard: in that situation it would be VERY hard to tell the difference between crashed and not crashed :)
<5> toany: remove their access to openoffice.
<6> toany: eliminate users (method of your choosing) until the remaing ones do not want to crash it
<7> and aside from that, if you're running a multiheaded X server, you should have a huge swap partition anyways.
<2> hobbs: i can't really prove that, they say they did nothing
<5> process accounting!
<2> tilrman: it is not an option for me
<3> toany: improve your evidence collection then :)
<2> hobbs: until then..?
<6> you only have to eliminate one if you use the proper means :-)
<2> integral: what do you mean by process accounting?
<3> toany: no until then. Get started now ;)
<5> it's a means of accounting for processes.
<7> Khisanth, he want's to allow his users to run multiple open office instances on 512 ram.
<5> Alternatively, I'd tell your users to find a better sysadmin.
<7> lol
<3> toany: and replace the openoffice binary with a shell script that prints "The system is currently too low on memory to run OpenOffice; please try again in a few minutes"
<7> LOL
<2> hobbs: *what do i do* until then?
<3> toany: you don't do anything "until then" because you make then now :)
<7> toany, nothing.
<2> integral: i am the better sysadmin :D
<7> that's unbeleivably sad.
<7> and I can't even spell.
<2> bluebeard: do i look that bad?
<5> uhuh, no. You do not know what Berkeley process accounting is. A better sysadmin would actually know about UNIX.
<7> yes
<0> hobbs: Hrm. I can get an unmetered 1gbs port for $1000 a month
<0> It's so worth it
<3> integral: I know what it is! It's "that option that I never know whether to enable". But then again I don't admin anyone's machines but mine ;)
<2> integral: i am quite new to gnu/nix, at least as an admin
<5> hobbs: lastcomm is quite handy to figure out what your users did to break stuff :)
<5> buu: !?!
<3> buu: If you do want to get something a bit beefier than what you've got, you might consider splitting it with me
<3> buu: but, uh, not that ;)
<0> hobbs: Ok, we'll split the $800 one,
<7> couldn't open file '/var/log/pacct': No such file or directory
<2> hobbs: however, do you admit gnu/nix would be more simple to administer if it featured per user limitation?
<5> /etc/init.d/acct on
<3> toany: marginally.
<5> toany: hard partitioning is not a Unix feature. Try something like VMS, z/VM, etc
<0> Why on earth would you charge $129 for a amd1400/512 and $199 for an amd3000..
<0> On 100mbs
<0> I bet that's really over sold.
<7> hmm...
<7> I think I've hit my limit of productivity today
<7> cheers!
<3> toany: it would also take accounting code that doesn't exist. Get writing :)
<2> hobbs: they say bsd features per user limitation
<7> GAH
<7> do you know what BSD stands for?
<5> actually I'd guess that something like solaris has better support
<8> i wonder if rename can rename just a part of a file name, leaving the rest as it is
<5> moz_: rename "foo123", "foo456"!
<2> bluebeard: bsd stands for "bondage-slave-discipline" or something like that, right?
<5> it's a misspelling of "LSD"
<8> integral, well, no, because foo can be different in a group of files
<3> haha
<0> hahaha
<5> moz_: well one would write _code_. that's what programmers do.
<0> I think that might deserve a bash quote
<8> i'd like something like this
<2> bluebeard: oops, that had an extra "m" (bsdm)
<3> Actually that's BDSM
<2> bluebeard: then i guess it's some recursive acronym
<8> perl -e 'rename ' "(.*?)foo", "$1bee" '
<0> No we were just joking
<0> It doesn't exist
<8> is that possible?
<0> moz_: HEY MAYBE TRY IT
<5> moz_: perldoc -f glob. and use a loop.
<1> glob. To access this perldoc please type, at a command line, 'perldoc -f glob'. You may also find it at http://perldoc.perl.org/functions/glob.html
<8> buu, i tried but it doesn't work
<3> moz_: yes. If you want to rename a file named "(.*?)foo" to "bee"
<0> moz_: Excellent. Now you've learned something.
<5> for (glob "*foo") { /(.*)foo/ and rename $_, "${1}bee" }
<8> buu, pls ...
<6> moz_: there is a perl script called 'rename' which is a convenient wrapper around the rename syscall and s///
<0> moz_: Whatis "pls" ?
<3> tilrman: yes, I explained that earlier. He said "yeah, that's what I want" and then ignored it
<0> tilrman: Not quite.. it's actually a wrapper around eval and rename
<8> integral, why do i need a for cycle?
<3> moz_: because you want to rename more than one file?
<5> moz_: umm, because for is how we take a list of things, and do something for each one...
<8> hobbs, let's suppose i want to rename just one file but i want to use this syntax:
<6> hobbs: ah, didnt check the scroll back
<5> moz_: My code works. Just use it.
<8> integral, ok, but i'd like to learn too
<5> Well try learning perl...
<4> the figure out what his code is doing
<4> s/the//
<6> buu: true . . . but using much besides s/// in that eval usually isnt very interesting :-)
<5> I'm amazed that someone who knows perl doesn't know what a for loop does.
<3> moz_: you don't want to use anything like the syntax you have unless YOU WANT CODE THAT DOESN'T WORK.
<2> hobbs: anyway, let me make sure i understand your solution well enough: if i allow them to have a maximum of three logins, in order for me to make them incapable of crashing my machine, and if i want them to use a maximum memory of 150 mb, then i should limit <processes and their children> to AT MOST <150 (maximum memory) / 3 (maximum number of sessions)>, which is 50 mb. am i right?
<7> toany, berkleysoftwaredistrobution
<3> toany: right. Which probably isn't enough, which is why the solution is to buy more RAM :)
<7> my space key doesn't seem to wanna work
<2> bluebeard: well, it should stand for BsdSoftwareDistribution. i like recursive acronyms
<8> integral, is your command supposed to stay into a perl file?
<8> integral, i asked for a linux command-line command which uses rename perl function
<5> moz_: just wrap the perl -e stuff around it...
<9> why the **** would someone log in thrice anyway? be a real admin and install screen
<7> lol
<7> jpeg, I like your crude artifacts
<3> jpeg: I was thinking that myself :)
<2> hobbs: and what is the name of that ulimit flag that refers to <max memory of any <process and all its children>>?
<2> jpeg: what about su?
<9> what about it?
<3> toany: -v. But you actually want to deal with limits.conf, not ulimit directly
<2> hobbs: i mean, how does the ulimit manual refer to <max memory of any <process and all its children>>? (because it has some very techie names)
<2> hobbs: i mean, i want both the flag (which you already gave me) and the way they call it :)
<2> hobbs: and, btw, thank you
<2> :)
<3> toany: "memory" :)
<5> ugh, too tedchnical!
<2> jpeg: does it imply login, or is it like screen?
<4> "stuff"
<3> toany: the "of a process and its children" is ***umed in the definition of resource limits
<2> hobbs: oh, that was quite plain
<2> hobbs: the word, i mean
<2> ;)
<9> toany: sense no make start
<7> toany, su? why would an ordinary user SU?
<2> hobbs: oh, so i need to setup the definitions of resource limits?
<7> holy ****
<2> bluebeard: su another user
<3> toany: you make less and less sense as time goes on
<7> can I just say, completely wrong channel
<2> bluebeard: i mean su their own user from another user
<3> toany: I mean THAT IS WHAT RESOURCE LIMITS ARE. THAT'S WHAT THEY DO. THAT IS HOW THEY ARE DEFINED.
<7> toany, that's not a good thing.
<7> why would you want to let them do that?
<6> bluebeard: they will be using 'su' to remove the draconian ulimits their admin has placed on the system ;-)
<7> it doesn't infer any menefits.
<2> bluebeard: do you think i am too permissive?
<3> bluebeard: because he's an amazingly goot sysadmin :)
<3> good, too
<2> bluebeard: i thought that was.. nice
<0> infi: English football fans in Germany for the World Cup likely to sing all the old favourites: "Stand Up If You Won the War," and "Two World Wars and One World Cup, Doodah, Doodah."
<2> bluebeard: i mean i like to allow them many right, except to.. crash my box
<0> Hrm. I was aiming at integarl
<2> *many a right
<10> well, you missed.
<7> toany, it's typically better to work from 0 permisssions upwards, than from fullaccess downwards.
